Ответ:
x=2/5
Step-by-step explanation:
625^x=5^2/5^x
5^4x=5^2-x
4x=2-x
4x plus x=2
5x=2
x=2/5
Ответ:
5x = 16 (subtract 29 from both sides)
x = 16/5.
That is the answer, I don't know where you got the value of 5 but it doesn't make sense. To prove it, let's try put it into the equation:
5x5 + 29 =45
25 + 29 = 45
Wrong! 25 + 29 = 54.
